[Boatanchors] Collins 310B-3

[wb6nyr]

Just acquired a 310B-3 and manual scarcely describes use of the antenna tuning network versus use of the plate plugin coil.  Not much on network searches.  Was hoping some OT could help with how these are setup.  Only one antenna network coupler plugin is supplied. Manual says two required to cover ham bands.  Think the coupler taps can be adjusted to change band range.  May have been convenient to have two preset couplers to just swap out to change lower and upper band range coverage quickly.Think instuctions say if using antenna coupler for all ham bands then have to bypass the plate plugin coil which is band specific.Any help from the would be appreciated.Sent from wb6nyr smartphone
